    • A linear body drive device capable of safely and reliably operating a linear body is provided. A linear body insertion device includes a drive portion, an operation portion, a sensor portion and a processing portion serving as a measurement portion, and an output portion serving as a notification portion. The drive portion drives a linear body having flexibility. The operation portion includes an input member (an operation lever) operated by an operator for controlling performance of the drive portion. The sensor portion included in the measurement portion detects compressive force in a direction of longitudinal axis applied to the linear body, based on a degree of bending of the linear body driven by the drive portion. The output portion provides notification of data of compressive force detected by the measurement portion.
    • 提供了能够安全可靠地操作线状体的直线体驱动装置。 直线体插入装置包括驱动部分,操作部分,传感器部分和用作测量部分的处理部分,以及用作通知部分的输出部分。 驱动部驱动具有柔性的线状体。 操作部包括由操作者操作以控制驱动部的性能的输入部件(操作杆)。 包含在测量部分中的传感器部分基于由驱动部分驱动的直线体的弯曲程度来检测施加到线状体的纵轴方向上的压缩力。 输出部分提供由测量部分检测的压缩力数据的通知。

    • A measurement device can detect a degree of bending of a linear body with a sensor when compressive force in a direction of longitudinal axis is applied to the linear body as a result of contact of a tip end of the linear body with an obstacle. Then, the detected degree of bending of the linear body is converted to compressive force in the direction of longitudinal axis applied to the linear body based on predetermined correlation between the degree of bending and the compressive force, so that presence of an obstacle in a direction of travel of the linear body can be sensed based on increase in the compressive force. In addition, as the same measurement device is applicable to linear bodies of various shapes and materials, cost effectiveness is achieved.
    • 由于线状体的前端与障碍物的接触,测量装置可以利用传感器检测线状体的弯曲程度,因为沿着纵向方向的压缩力被施加到线状体。 然后,基于预定的弯曲度与压缩力之间的相关关系,将线状体的检测度转换为施加于线状体的纵轴方向的压缩力,使得在方向上存在障碍物 可以基于压缩力的增加来感测线状体的行进。 此外,由于相同的测量装置适用于各种形状和材料的线状体,因此实现了成本效益。
